예제

다음 코드에는 테스트할 클래스와 메서드가 포함되어 있습니다.

using System;

namespace BankAccountNS
{
    public class BankAccount
    {
        private string custName;
        private double bal;

        public BankAccount(string customerName, double balance)
        {
            custName = customerName;
            bal = balance;
        }

        public double Balance
        { get { return bal; } }

        public void Debit(double amount)
        {
            if (amount < 0)
                throw new ArgumentOutOfRangeException("amount");
            bal -= amount;
        }
    }
}

Imports System

Namespace BankAccountNS
    Public Class BankAccount
        Private customerName As String
        Private bal As Double

        Public Sub New(ByVal customerName2 As String, ByVal balance As Double)
            customerName = customerName2
            bal = balance
        End Sub

        Public ReadOnly Property Balance() As Double
            Get
                Return bal
            End Get
        End Property

        Public Sub Debit(ByVal amount As Double)
            If amount < 0 Then
                Throw New ArgumentOutOfRangeException("amount")
            End If
            bal -= amount
        End Sub
    End Class
End Namespace

아래의 테스트는 성공합니다. 이 테스트에서는 다음과 같은 데이터가 들어 있는 sample.mdb Access 데이터베이스를 사용합니다.

Name	Balance	양
Jorg Bott	100	25
Pedro Ruivo	70	60
Mandar Samant	75	71.25
Russell King	159	158
Jun Cao	11.99	11.22
